Interesting... I guessed that maybe the fact that I was using /usr/bin/ruby and there was a separate /usr/local/bin/ruby might be a problem. They are the same version ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-linux] and in fact, one turns out to be a symlink to the other(!) but using /usr/bin/ruby in the shebang fails, while using /usr/local/bin/ruby in the shebang succeeds. Any ideas? Thanks, Grem -- Posted via http://www.ruby-forum.com/.
